Sharp corners replaced by radii.
Wall thickness s ≥ 0,1 d;
where possible not< 2mm. |
| |
Designs a), b) and c) allow easier tooling. |
| |
Avoid sharp corners on the diameters
d1 and d2.
Use radii instead. |
| |
Aim for round break-throughs.
Min. wall thickness s = 2mm. |
| |
Replace spanner faces with bores if the separation s is too little. |
| |
If the design calls for split dies keep the distance from the tooth base and crown > 2mm. |
| |
Ratio of d:b max. 1:2 |
| |
Apply radii and 5 degree draft to cut outs. |
| |
Keep the thickness of the
tongue b ≥ 2mm;
Apply radius to the junction |
| |
Base thickness b ≥ 2mm |
| |
Avoid pointed contours b ≥ 1mm |
|
Profiles on front faces can be produced without split dies if the depth
b2 ≤ and the height b3 ≤ 0,1 x b1 is held.
Draft ≥ 5 degrees. |
| |
Module m ≥ 0,5 |
| |
Undercuts, threads and cross bores cannot be produced in sinters. |
| |
Replace diamond knurl with straight knurl or profile. |
| |
Design outside edges straight or with
30 degree chamfers. Inner faces rounded. |
| |
In conical components, allow a cylindrical ring face b ≥ 0,5 mm |
